In 2054 AD, some unexplained changes occurred in the cosmic space where the earth is located, thus triggering the "extraordinary energy tide" phenomenon on the earth.
Abnormal energy beyond common sense is something the human body cannot bear. The earth's population has dropped by four-fifths, and lucky humans have mutated together with the environment, establishing safe zones where the "tide" intensity is less than a certain value. Under the huge threat of animals and plants with higher probability and severity on one side, they held on to their position of survival.
Before the new society was established, humans shed blood for many years, but in the end, they occupied the top of the planet's pyramid with a new attitude. At this time, a "big surprise" appeared - a huge space crack appeared at approximately 27︒8´ north latitude and 107︒7´ to 120︒3´ east longitude.
On the other side of the rift is the Eldar planet.
